Hi Doctor, Hope you are doing good. I have a problem of premature Ejaculation. I am good in doing romance, oral sex. But the time it comes for penetration, immediately in a minute semen ejaculate. Though i am a little fat (76kg) I try to eat all healthy meals, even i do not take high amount of food. Yes, I do smoke, a packet in a day and its been 1yr i have stoped alcohol, I take but very very rare. Need 1 suggestion, can i have Viagra pill? This is all about me. Kindly let me know the solution, exercise etc which will help me to last longer on a bed.
